According to Android Central, Half-Life 2 is coming to the Nvidia Shield. How do they know this? Well, apparently Nvidia and/or Valve sent them a large green crowbar with the Half-Life 2 and Nvidia Shield logos, and the tagline “What Would Gordon Do?” After the earlier announcement of Portal, which runs on the Source Engine as well, this announcement makes sense. Sending a press outlet a giant crowbar to announce it? It’s unorthodox — but not that unorthodox, and concise, at least. But hey, at least a gaming classic is coming to Android, right?
